1 claim. (c1. 4.-228) This invention relates to disinfectant dispensingdevices particularly as used in flush tanks of toilet bowls, and inparticular a container having a sealed filling plug in the upper endwith a valve body threaded on a neck extended from the lower end, with afloat actuated valve positioned in said valve body and with an extendedvent tube extended from the valve body upwardly beyond the upper end ofthe container.

The purpose of this invention is to provide vacuum relieving means in aoat actuated disinfectant container whereby a small amount only ofdisinfectant is dispensed each time the tank is llushed.

Various types of float actuated dispensing containers have been providedfor flush tanks of toilet bowls, how ever, it is dilcult to relieve thevacuum in a sealed container so that substantially measured quantitiesof disinfectant are positively discharged when the tank is flushed. Withthis thought in mind this invention contemplates a iloat actuated valvefor a disinfectant container, where the container is adapted to bepositioned in a body of water in which the valve is provided with anextended vertically disposed tube that admits air from the upper end ofthe tank to the interior of the disinfectant container.

The object of this invention is, therefore, to provide means forincorporating an extended vent in a valve body of a float actuateddispenser valve.

Another object of the invention is to provide an automatically operatingdispensing container that may be installed in a flush tank of a toiletbowl by a hook extended over the upper edge of a wall of the tank andwithout permanent attaching means.

A further object of the invention is to provide a lloat actuateddispensing container having an upwardly extended vent in which thecontainer is of a simple and economical construction.

With these and other objects and advantages in view the inventionembodies a container having threaded necks extended from the ends with asealing cap positioned on the neck on the upper end, a valve bodythreaded on the neck extended from the lower end and in which the valveof the said valve body is positioned to be actuated by a oat and whereinthe valve body is provided with a tube extended from one side thereof toa point positioned above the upper end of the container.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawing, wherein:

Figure 1 is a vertical section through the dispensing container with thevalve shown in the closed position.

Figure 2 is a similar view showing the lower end of the container withthe parts on an enlarged scale and showing the valve in the openposition wherein disinfectant is being discharged from the container.

Figure 3 is a similar view, on a reduced scale, also showing the valvein the open position and showing the valve surrounded by water in thetank whereby disinfectant is prevented from flowing from the container.

l 2,726,406 ce Patented Dec. 13, 1955 As illustrated in Fig. 1 thecontainer 10 is providedy with a threaded neck 16, at the upper end,providing a lilling opening, and a cap 17 threaded Von'the neck 16 andprovided with a sealing washer 18 provides va 'sealed closure for theupper end of the container.

The lower end of the container is provided with a similar threaded neck19 upon which the valve body 12 is threaded and a sealing washer 20 isprovided between the end of the neck 19 and the valve body. A neck 21extends downwardly from the valve body 12 and a frustoconical shapedvalve seat 22 for the valve 11 is provided in the intermediate part ofthe body. The lower end surface of the neck 2.1 is provided with crossgrooves 23 that communicate with a bore 24 which extends through thevalve body and through which the valve stem 14 passes and in the upperend of which the valve seat 22 is positioned.,

A knurled nut 2S is threaded on a threaded section of the stem 14, andthe lower part of the threaded section of the stem is threaded into aboss 26 on one side of the oat 13. By this means the nut 25 is adjustedon the stem 14 to regulate the opening movement of the valve 11 wherebythe amount of disinfectant discharged each time a toilet bowl is hushedis adapted to be regulated.

As illustrated in Figure 1, the upper surface of the knurled nut 25 isspaced from the end surface of the neck 21 of the valve body 12 when thelevel of liquid in the tank 29 is below the ball 13 and as the tanklills with water whereby the water passes upwardly, as illustrated inFigure 2, the ball or float 13 moves the valve stem and valve upwardlyuntil the upper surface of the nut 25 engages the end surface of theneck 21 and disinfectant flows over the valve 11, through the bore 24and the grooves of the cross 23, as indicated by the arrows 21, untilthe water level passes upwardly over the lower part of the valve body,as shown in Figure 3. With liquid, such as water, surrounding the lowerpart of the valve body, the grooves 23 are closed with the water as soonas the pressure of the water and the pressure of the lluid in the tank10 is equalized. The escape channels for the disinfectant remain closedby the water until the water level drops to the position shown in Figure2 whereby the disinfectant passes outwardly through the grooves 23 intowater of the tank.

The valve body 12 is also provided with a side opening 27, from theouter end of which the vent tube 15 extends and, as illustrated in Fig.l the upper end of the tube 15 extends to a point 28, which is above thewater level of the tank 29.

The container 10 is also provided with a hanger or hook 30 with whichthe dispensing container is suspended from the upper edge of a wall ofthe tank.

With the parts positioned in this manner the valve is normally retainedin the open position as long as water in the tank extends upwardly abovethe valve body and upon flushing of the tank the float drops downwardlywith the liquid level, as illustrated in Fig. 2 whereby disinfectant owsthrough the bore 24 of the lower end of the valve body into the tank asindicated by the arrows 31, the displaced disinfectant in the tank beingreplaced with air through the vent. As the liquid level continues todrop the float draws thevalve 11 downwardly against the valve seat 22and the valve is closed. By this means disinfectant is discharged onlyas the valve travels downwardly or upwardly with the liquid level andoat.

The container may readily be refilled through the cap 17 and it may alsobe removed to clean the valve body.

It will be understood that modications within the Scope of the appendedclaim may be made in the design and arrangement of the parts withoutdeparting from the spirit of the invention.

What is claimed is:

A disinfectant container valve comprising a valve body having aninternally threaded upper end with a neck of reduced diameter extendedfrom the lower end, said neck having a vertically disposed bore extendedtherethrough witha valve seat at the upper end of the bore and spacedbelow the threads and with cross grooves in the end surface of the lowerendsaid valve body having a laterally positioned opening extended from apoint above the valve seat, an upwardly disposed tube extended from saidopen ing providing a vent, a valvepositioned on said valve seat, a stemextended from said valve through the bore of the neck, a hollow hallcarried by the lower end of the stem providing a oat, and a nut threadedon said stem for regulating the opening movement of the valve.
